Title	Airborne Contamination Over the Limit in the Feed Materials Building
Event Description	{{#Wiki_filter:An unplanned contamination event occurred on February 22, 2009. This is a reportable event in accordance with 10 CFR 40.60 paragraph (b)(1) based on an unplanned event that results in additional radiological control being required for more than 24 hours. The 24 hour period ended at 10:30 on February 23, 2009. The additional control imposed was wearing a half face respirator in the 6th floor of the Feed Materials Building. The Feed Materials Building converts uranium ore concentrates into uranium hexafluoride. Air samples from the 6th floor were analyzed and the airborne radioactivity average was approximately 6.73 e-11 �Ci/ml. The airborne radioactivity exceeded the MTW [Honeywell Metropolis Facility] action level of 30% of a DAC (5.00 e-11 �Ci/ml). One DAC is 1.7e-10 �Ci/ml. Uranium tetrafluoride (green salt) was the material that was airborne on the 6th floor. A release point could not be determined. The air samples indicate that the air emission occurred on the northwest side of the building likely to be from a release of material from the green salt elevator and conveyor system. See similar event number 44857 on 2/17/09. }}[[Event description::Description::{{#Regex_clear:An unplanned contamination event occurred on February 22, 2009.
